LENOVO WAS SHOWING off its new workstation line at GDC, the S10 and D10. Since GDC is about game development, not game play, it makes a lot of sense. The two machines are both Intel based, the S10 is single core, the D10 is dual core. According to Lenovo, and I do agree, what's different from a workstation from a PC is better construction, more expandability, more slots and a bigger PSU. On the less physical side, it also has ISV certifications, something you really need before you try and run a $50K CAD package on one.
